POWER UP WITH THE LONGEST IRON IN GOLF - The breakthroughs in distance and ball speed of the JPX-850 are achieved through Mizuno’s Power Frame design, which greatly increases the rebound area of the clubface. In addition, the Power Frame positions weight in the extreme corners of the club head to increase stability on off-center shots, maximizing forgiveness and consistent distance.
Equally as important, the innovative Power Frame design ensures ball speeds are consistently high across the entire clubface and that the high COR is not created at the expense of feel or control. The JPX-850 delivers more distance, with more solid feel than any other iron in the game.
